France faces black‑day traffic jam on August 1, 2026
Bison Futé classified Saturday 1 August 2026 as a black day for traffic across France, following a red‑day forecast for Friday 31 July. The agency warned of extremely dense traffic on the main routes serving the Normandy coast, the Atlantic façade, the South‑East quarter, Auvergne‑Rhône‑Alpes and the Mediterranean arc. Peak congestion was expected on the A6 and A10 autoroutes in the late morning, with the A63 motorway between Bayonne and Bordeaux already reopened in both directions. On the A11 near Angers, more than 13 km of slowdown was recorded. At midday the total length of traffic jams exceeded 1 000 km, reaching a peak of 1 041.2 km at 11:50 a.m. Bison Futé estimated the weekend could cost several hundred million euros in fuel waste, lost time and disrupted economic activity. Motorists were advised to avoid the Mont‑Blanc tunnel between 11 h and 22 h and, where possible, to travel before 5 h or after 21 h.
